The probability that he will get at least three hits in the game is 0.5226 or approximately 52.26%. This is a high probability of getting at least three hits out of five at-bats.

In a single at-bat, a high school baseball player has a 0.319 batting average. In the forthcoming game, he'll have five at-bats. We must determine the probability that he will receive at least three hits during the game. At least three hits are required. As a result, we'll have to add up the probabilities of receiving three, four, or five hits separately.

We'll use the binomial probability formula since we have binary outcomes (hit or no hit) and the number of trials is finite (5 at-bats):P(X=k) = C(n,k) * p^k * q^(n-k)where C(n,k) represents the combination of n things taken k at a time, p is the probability of getting a hit, q = 1 - p is the probability of not getting a hit, and k is the number of hits.

The probability of getting at least three hits is:P(X ≥ 3) = P(X = 3) + P(X = 4) + P(X = 5)P(X=3)=C(5,3)*0.319³*(1-0.319)²=0.324P(X=4)=C(5,4)*0.319⁴*(1-0.319)=0.172P(X=5)=C(5,5)*0.319⁵*(1-0.319)⁰=0.0266P(X ≥ 3) = 0.324 + 0.172 + 0.0266 = 0.5226 or approximately 52.26%.

Therefore, the probability that he will get at least three hits in the game is 0.5226 or approximately 52.26%. This is a high probability of getting at least three hits out of five at-bats.

a. The probability that a sample of 49 has a sample mean greater than 37 is approximately 0.9996.

b. The probability that a sample of 49 has a sample mean at most 43 is approximately 0.9192.

c. To calculate the probabilities for the given sample means, we can use the Central Limit Theorem. According to the Central Limit Theorem, as the sample size increases, the distribution of sample means approaches a normal distribution, regardless of the shape of the population distribution.

Given:

Mean (μ) = 40

Standard Deviation (σ) = 17

Sample size (n) = 49

a. Probability of sample mean greater than 37:

To calculate this probability, we need to find the area under the normal curve to the right of 37. We can use the z-score formula:

z = (x - μ) / (σ / √n)

where x is the value we are interested in (37), μ is the population mean (40), σ is the population standard deviation (17), and n is the sample size (49).

Substituting the values:

z = (37 - 40) / (17 / √49) = -3 / (17 / 7) ≈ -1.235

Using a standard normal distribution table or statistical software, we can find the probability associated with a z-score of -1.235, which is approximately 0.1098.

However, since we are interested in the probability of a sample mean greater than 37, we need to subtract this probability from 1:

Probability = 1 - 0.1098 ≈ 0.8902

Therefore, the probability that a sample of 49 has a sample mean greater than 37 is approximately 0.8902 or 89.02%.

b. Probability of sample mean at most 43:

To calculate this probability, we need to find the area under the normal curve to the left of 43. Again, we can use the z-score formula:

z = (x - μ) / (σ / √n)

where x is the value we are interested in (43), μ is the population mean (40), σ is the population standard deviation (17), and n is the sample size (49).

Substituting the values:

z = (43 - 40) / (17 / √49) = 3 / (17 / 7) ≈ 1.235

Using the standard normal distribution table or statistical software, we can find the probability associated with a z-score of 1.235, which is approximately 0.8902.

Therefore, the probability that a sample of 49 has a sample mean at most 43 is approximately 0.8902 or 89.02%.

a. The probability that a sample of 49 has a sample mean greater than 37 is approximately 0.9996 or 99.96%.

b. The probability that a sample of 49 has a sample mean at most 43 is approximately 0.9192 or 91.92%.

Itô's formula states that for a function f and a Brownian motion Bt, the integral f(Bt)−f(0) can be expressed as a sum of two terms: a deterministic term and a stochastic term. The deterministic term is the integral of the drift of f, and the stochastic term is the integral of the diffusion of f.

[tex]\int\limits^t_0 {0.5e^(B_s) } \, ds[/tex]

The first term on the right-hand side is the deterministic term, and the second term is the stochastic term. The deterministic term represents the expected increase in e^Bt due to the drift of f, and the stochastic term represents the unpredictable change in e^Bt due to the diffusion of f.

To see why this is true, we can expand the integrals on the right-hand side. The first integral, e^(B_t)-1 = \int\limits^t_0 {0.5e^(B_s) } \, ds + \int\limits^t_0 {e^(B_s)d} \, Bs, is simply the expected increase in e^Bt due to the drift of f. The second integral,

[tex]\int\limits^t_0 {e^(B_s)d} \, Bs[/tex], is the integral of the diffusion of f. This integral is stochastic because the increments of Brownian motion are unpredictable.

Therefore, Itô's formula shows that the difference between e^Bt and 1 can be expressed as a sum of two terms: a deterministic term and a stochastic term. The deterministic term represents the expected increase in e^Bt due to the drift of f, and the stochastic term represents the unpredictable change in e^B t due to the diffusion of f.

i. The distribution that could be used to model Y, the number allocated to the student chosen, is the discrete uniform distribution. In this case, the discrete uniform distribution assumes that each student has an equal probability of being chosen, and there is no preference or bias towards any particular student.

ii. E(Y) (the expected value of Y) for a discrete uniform distribution can be calculated using the formula:

E(Y) = (a + b) / 2

where 'a' is the lower bound of the distribution (1 in this case) and 'b' is the upper bound (100 in this case).

E(Y) = (1 + 100) / 2 = 101 / 2 = 50.5

So, the expected value of Y is 50.5.

sd(Y) (the standard deviation of Y) for a discrete uniform distribution can be calculated using the formula:

sd(Y) = sqrt((b - a + 1)^2 - 1) / 12

where 'a' is the lower bound of the distribution (1) and 'b' is the upper bound (100).

sd(Y) = sqrt((100 - 1 + 1)^2 - 1) / 12

= sqrt(10000 - 1) / 12

= sqrt(9999) / 12

≈ 31.61 / 12

≈ 2.63

So, the standard deviation of Y is approximately 2.63.

iii. The probability that the first student to enter the room receives the chocolate can be determined by calculating the probability of Y being equal to 1, which is the number assigned to the first student.

P(Y = 1) = 1 / (b - a + 1)

The derivative of the function r(x) OR r' is given by :

r'(x) = (27(4x - 1)/(7x + 3)^2 - 36x/(7x + 3)) / (4x - 1)^2.

To find the derivative of the function r(x) = p(x)/q(x), we can use the quotient rule. The quotient rule states that if we have two functions u(x) and v(x), then the derivative of their quotient is given by:

r'(x) = (u'(x)v(x) - u(x)v'(x)) / (v(x))^2

Let's calculate r'(x) step by step using the given functions p(x) and q(x):

p(x) = 9x / (7x + 3)

q(x) = 4x - 1

First, we need to find the derivatives of p(x) and q(x):

p'(x) = (d/dx)(9x / (7x + 3))

      = (9(7x + 3) - 9x(7))/(7x + 3)^2

      = (63x + 27 - 63x)/(7x + 3)^2

      = 27/(7x + 3)^2

q'(x) = (d/dx)(4x - 1)

      = 4

Now, we can substitute these values into the quotient rule to find r'(x):

r'(x) = (p'(x)q(x) - p(x)q'(x)) / (q(x))^2

      = (27/(7x + 3)^2 * (4x - 1) - (9x / (7x + 3)) * 4) / (4x - 1)^2

      = (27(4x - 1)/(7x + 3)^2 - 36x/(7x + 3)) / (4x - 1)^2

So, r'(x) = (27(4x - 1)/(7x + 3)^2 - 36x/(7x + 3)) / (4x - 1)^2.

The equation of the normal line to the surface at the same point can be expressed parametrically as x = 1 + t, y = 2 + 2t, and z = 3 + 3t, where t is a parameter representing the distance along the line.

The equation of the tangent plane to the surface xyz = 6 at the point (1, 2, 3) is given by the equation x + 2y + 3z = 12.

To find the equation of the tangent plane to the surface xyz = 6 at the point (1, 2, 3), we first need to determine the partial derivatives of the equation with respect to x, y, and z. Taking these derivatives, we obtain:

∂(xyz)/∂x = yz,

∂(xyz)/∂y = xz,

∂(xyz)/∂z = xy.

Evaluating these derivatives at the point (1, 2, 3), we have:

∂(xyz)/∂x = 2 x 3 = 6,

∂(xyz)/∂y = 1 x 3 = 3,

∂(xyz)/∂z = 1 x 2 = 2.

Using these values, we can form the equation of the tangent plane using the point-normal form of a plane equation:

6(x - 1) + 3(y - 2) + 2(z - 3) = 0,

6x + 3y + 2z = 12,

x + 2y + 3z = 12.

This is the equation of the tangent plane to the surface at the point (1, 2, 3).

To find the equation of the normal line to the surface at the same point, we can use the gradient vector of the surface equation evaluated at the point (1, 2, 3). The gradient vector is given by:

∇(xyz) = (yz, xz, xy),

Evaluating the gradient vector at (1, 2, 3), we have:

∇(xyz) = (2 x 3, 1 x 3, 1 x 2) = (6, 3, 2).

Using this vector, we can express the equation of the normal line parametrically as:

x = 1 + 6t,

y = 2 + 3t,

z = 3 + 2t,

where t is a parameter representing the distance along the line. This parametric representation gives us the equation of the normal line to the surface at the point (1, 2, 3).

To evaluate the integral ∫([tex]x^{2}[/tex] - [tex]a^{2}[/tex])/[tex]x^{4}[/tex] dx, where a is a constant, we can use the substitution x = a sec(θ) in order to simplify the expression.

Let's apply the substitution x = a sec(θ) to the integral. We have dx = a sec(θ) tan(θ) dθ and [tex]x^{2}[/tex] -[tex]a^{2}[/tex] = [tex]a^{2}[/tex] sec^2(θ) - [tex]a^{2}[/tex] = [tex]a^{2}[/tex] (sec^2(θ) - 1).

Substituting these expressions into the integral, we get:

∫(x^2 - a^2)/x^4 dx = ∫([tex]a^{2}[/tex] (sec^2(θ) - 1))/([tex]a^{4}[/tex]sec^4(θ)) (a sec(θ) tan(θ) dθ)

= ∫(1 - sec^2(θ))/[tex]a^{2}[/tex] sec^3(θ) tan(θ) dθ.

Simplifying further, we have:

= (1/a^2) ∫(1 - sec^2(θ))/sec^3(θ) tan(θ) dθ

= (1/a^2) ∫(1 - sec^2(θ))/(sec^3(θ)/cos^3(θ)) (sin(θ)/cos(θ)) dθ

= (1/a^2) ∫(cos^3(θ) - 1)/(sin(θ) cos^4(θ)) dθ.

Now, we can simplify the integrand further by canceling out common factors:

= (1/a^2) ∫(cos^2(θ)/cos(θ) - 1/(cos^4(θ))) dθ

= (1/a^2) ∫(1/cos(θ) - 1/(cos^4(θ))) dθ.

To evaluate the integral ∫​(3x+1)³ / √(9x²+6x+10) dx, we can use the substitution rule. By letting u = 9x² + 6x + 10, we can simplify the integral and find the antiderivative. The final result involves trigonometric functions and natural logarithms.

To solve the integral ∫​(3x+1)³ / √(9x²+6x+10) dx, we can use the substitution rule. Let's choose u = 9x² + 6x + 10 as our substitution. Taking the derivative of u with respect to x, we have du/dx = 18x + 6. Rearranging, we can express dx in terms of du: dx = (du / (18x + 6)). Now, substitute these expressions in the integral.

∫​(3x+1)³ / √(9x²+6x+10) dx = ∫​(3x+1)³ / √u * (du / (18x + 6))

We can simplify this further by factoring out the common factor of (3x + 1)³ from the numerator:

∫​(3x+1)³ / √u * (du / (18x + 6)) = (1/18) ∫(3x+1)³ / √u * du

Now, we can use a new variable v to represent (3x + 1):

∫ v³ / √u * du

To further simplify the integral, we can make another substitution by letting w = √u. Then, dw = (1/2√u) du.

The integral becomes:

(1/2) ∫ v³ / w * dw = (1/2) ∫ v²w dw

Now, we can use the power rule for integration to find the antiderivative of v²w:

(1/2) * (v³w/3) + C = (v³w/6) + C

Substituting back the original expressions for v and w, we have:

(1/6) * (3x + 1)³ * √(9x² + 6x + 10) + C

Therefore, the antiderivative of (3x+1)³ / √(9x²+6x+10) dx is (1/6) * (3x + 1)³ * √(9x² + 6x + 10) + C.

Duf(-1,2) = -24/√5. The directional derivative of a function in a certain direction is the dot product of the gradient of the function at that point and the unit vector in the direction.

To find the directional derivative Duf(x,y) of the function f(x,y) = 6xy^2 + 7x^2 at the point (-1,2) and in the direction u = (2,1)/(√5), we first find the gradient of f(x,y) at (-1,2) which is (12, -24).

Next, we normalize the direction vector u to get u = (2/√5, 1/√5).

Finally, we take the dot product of the gradient and the normalized direction vector to get the directional derivative: Duf(-1,2) = grad f(-1,2) · u = (12, -24) · (2/√5, 1/√5) = -24/√5.

Imagine you are an air traffic controller responsible for guiding aircraft during landing procedures. To efficiently direct the planes, you need to determine the positions of the aircraft relative to a specific reference point, such as the control tower.

In this situation, overlaying a polar coordinate system allows you to represent the positions of the aircraft accurately. By choosing the control tower as the pole and extending the polar axis outward, you can use polar coordinates to specify the distance and direction of each aircraft from the control tower.

This polar coordinate system enables you to quickly identify the location of each aircraft, calculate the distances between them, and provide precise instructions for landing sequences. By using polar coordinates, you can effectively manage the airspace, ensure the safety of incoming aircraft, and prevent any potential collisions.

(a) The set of possible values of z₃ is {-2 + i√(12), -2 - i√(12)}.

 factorization of P(z) into linear factors over C is:

(c) P(z) = (z + 2 - i√(12))(z + 2 + i√(12))(z + 2 - i√(12))(z + 2 + i√(12))

(a) To find the values of z₃ that satisfy the equation P(z) = 0, we can rewrite the equation as z₆ + 4z₃ + 16 = 0. This is a sextic polynomial, which can be thought of as a quadratic equation in terms of z₃. Applying the quadratic formula, we have:

z₃ = (-4 ± √(4² - 4(1)(16))) / (2(1))

   = (-4 ± √(16 - 64)) / 2

   = (-4 ± √(-48)) / 2

Since we have a negative value inside the square root (√(-48)), we know that the solutions will involve complex numbers. Simplifying further:

z₃ = (-4 ± √(-1)√(48)) / 2

   = (-4 ± 2i√(12)) / 2

   = -2 ± i√(12)

Therefore, the set of possible values of z₃ is {-2 + i√(12), -2 - i√(12)}.

(c) To factorize the sextic polynomial P(z) = z⁶ + 4z³ + 16 into linear factors over C, we can use the solutions we found for z₃, which are -2 + i√(12) and -2 - i√(12).

Therefore, the sextic polynomial P(z) can be factorized over C as:

P(z) = (z + 2 + i√(12))(z + 2 - i√(12))

These linear factors represent the complete factorization of P(z) over the complex number field C.

The x-intercept of the given function is approximately -32.3.

The x-intercept of the given function can be found by setting y (or f(x)) equal to zero and solving for x.

So, we have:

2log(-3(x-1))-4 = 0

2log(-3(x-1)) = 4

log(-3(x-1)) = 2

Now, we need to rewrite the equation in exponential form:

-3(x-1) = 10^2

-3x + 3 = 100

-3x = 97

x = -32.3 (rounded to 1 decimal place)

Therefore, the x-intercept of the given function is approximately -32.3.

Note: It's important to remember that the logarithm of a negative number is not a real number, so the expression -3(x-1) must be greater than zero for the function to be defined. In this case, since the coefficient of the logarithm is positive, the expression -3(x-1) is negative when x is less than 1, and positive when x is greater than 1. So, the x-intercept is only valid for x greater than 1.

The graph of the function F(x) = |x| * 0.015 for x > 0 (sale) and F(x) = |x| * 0.005 for x < 0 (return) is a V-shaped graph with a steeper slope for positive values of x and a shallower slope for negative values of x.

To graph the function f(x) = |x| * 0.015 for x > 0 (sale) and f(x) = |x| * 0.005 for x < 0 (return), we will plot the points on a coordinate plane.

First, let's consider the positive values of x (sale). For x > 0, the function f(x) = |x| * 0.015. The absolute value of any positive number is equal to the number itself. Thus, we can rewrite the function as f(x) = x * 0.015 for x > 0.

To plot the points, we can choose different positive values of x and calculate the corresponding values of f(x). Let's use x = 1, 2, 3, and 4 as examples:

For x = 1: f(1) = 1 * 0.015 = 0.015

For x = 2: f(2) = 2 * 0.015 = 0.03

For x = 3: f(3) = 3 * 0.015 = 0.045

For x = 4: f(4) = 4 * 0.015 = 0.06

Now, let's consider the negative values of x (return). For x < 0, the function f(x) = |x| * 0.005. Since the absolute value of any negative number is equal to the positive value of that number, we can rewrite the function as f(x) = -x * 0.005 for x < 0.

To plot the points, let's use x = -1, -2, -3, and -4 as examples:

For x = -1: f(-1) = -(-1) * 0.005 = 0.005

For x = -2: f(-2) = -(-2) * 0.005 = 0.01

For x = -3: f(-3) = -(-3) * 0.005 = 0.015

For x = -4: f(-4) = -(-4) * 0.005 = 0.02

Now, we can plot the points on the coordinate plane. The x-values will be on the x-axis, and the corresponding f(x) values will be on the y-axis.

For the positive values of x (sale):

(1, 0.015), (2, 0.03), (3, 0.045), (4, 0.06)

For the negative values of x (return):

(-1, 0.005), (-2, 0.01), (-3, 0.015), (-4, 0.02)

Connect the points with a smooth curve that passes through them. The graph will have a V-shaped appearance, with the vertex at the origin (0, 0). The slope of the line will be steeper for the positive values of x compared to the negative values.

A) The probability that a person eating ice cream complies European Championship in soccer is 6/13.B) The probability that a person who is watching the European Football Championship eats ice cream is 6/11.C) The two events are not independent.

a) The probability of a person eating ice cream follows European Championship in soccer is to be determined. Given that 30% of the people follow soccer World Cup and eat ice cream. Then, using the formula of conditional probability, we get P(A|B) = P(A and B) / P(B).

Here, A: Eating ice cream follows European Championship B: Follow soccer World Cup

P(A and B) = 30%

P(B) = 65%

P(A|B) = P(A and B) / P(B) = 30/65 = 6/13

So, the probability that a person eating ice cream complies European Championship in soccer is 6/13.

b) The probability of a person who is watching the European Football Championship eating ice cream is to be determined. Again, using the formula of conditional probability, we get P(A|B) = P(A and B) / P(B).

Here, A: Eating ice creamB: Watching European Football Championship

P(A and B) = 30%

P(B) = 55% (As 55% eat ice cream)

P(A|B) = P(A and B) / P(B) = 30/55 = 6/11.

So, the probability that a person who is watching the European Football Championship eats ice cream is 6/11.

c) To check whether two events are independent or not, we need to see if the occurrence of one event affects the occurrence of another. So, we need to check whether the occurrence of eating ice cream affects the occurrence of following soccer World Cup.

Using the formula for the probability of independent events, we get

P(A and B) = P(A) x P(B) = 55/100 x 65/100 = 3575/10000 = 0.3575

But P(A and B) = 30/100 ≠ 0.3575

The average rate of change of f(x) on the interval [3, 3+h] is given by the expression (f(3+h) - f(3))/h.

To find the average rate of change of f(x) on the interval [3, 3+h], we can use the formula for average rate of change. The formula is (f(b) - f(a))/(b - a), where f(b) represents the value of the function at the upper bound, f(a) represents the value of the function at the lower bound, and (b - a) represents the change in the independent variable.

In this case, the lower bound is a = 3 and the upper bound is b = 3+h. The function f(x) is given as f(x) = 1/(x+4). So, we need to evaluate f(3) and f(3+h) to plug them into the formula.

Substituting x = 3 into f(x) = 1/(x+4), we get f(3) = 1/(3+4) = 1/7.

Substituting x = 3+h into f(x) = 1/(x+4), we get f(3+h) = 1/(3+h+4) = 1/(h+7).

Plugging these values into the formula, we have (f(3+h) - f(3))/(3+h - 3) = (1/(h+7) - 1/7)/h = (7 - (h+7))/(7(h+7)) = -h/(7(h+7)).

Therefore, the average rate of change of f(x) on the interval [3, 3+h] is given by the expression -h/(7(h+7)).

In summary, the average rate of change of f(x) on the interval [3, 3+h] is expressed as -h/(7(h+7)), obtained by using the formula for average rate of change and evaluating the function f(x) at the given bounds.

There are 2^4 = 16 possible outcomes for the tosses of the penny, nickel, dime, and quarter. There is only one way to get all four heads, and there are four ways to get three heads.

Therefore, the probability of obtaining at least three heads on the tosses is 5/16 = 1/8. If the first toss is a head, there are three possible outcomes for the remaining tosses: HHH, HHT, and HTH. Therefore, the probability of obtaining three heads if the first toss is a head is 3/8 = 1/4.

The probability of obtaining at least three heads on the tosses can be calculated as follows:

P(at least 3 heads) = P(4 heads) + P(3 heads)

The probability of getting four heads is 1/16, since there is only one way to get all four heads. The probability of getting three heads is 4/16, since there are four ways to get three heads (HHHT, HTHH, THHH, and HHHH). Therefore, the probability of obtaining at least three heads on the tosses is 1/16 + 4/16 = 5/16.

The probability of obtaining three heads if the first toss is a head can be calculated as follows:

P(3 heads | first toss is a head) = P(HHH) + P(HHT) + P(HTH)

The probability of getting three heads with a head on the first toss is 3/8, since there are three ways to get three heads with a head on the first toss. Therefore, the probability of obtaining three heads if the first toss is a head is 3/8.

To find the orthogonal trajectories of the family of curves given by y^6 = kx^6, we need to determine the differential equation satisfied by the orthogonal curves. Let's differentiate the equation with respect to x:

6y^5 dy/dx = 6kx^5. Now, we can express dy/dx in terms of x and y:

dy/dx = kx^5 / y^5. The condition for two curves to be orthogonal is that the product of their slopes is -1. Therefore, the slope of the orthogonal curves should be: dy/dx = -y^5 / (kx^5).

We can rewrite this equation as:

(kx^5 / y^5) (dy/dx) = -1.

Simplifying, we get:

(x^5 / y^5) (dy/dx) = -1/k.

Now, we have a separable differential equation. By rearranging and integrating both sides, we can obtain the equation for the orthogonal trajectories. Integrating, we have:

∫(x^5 / y^5) dy = -∫(1/k) dx.

Integrating both sides, we get:

(-1/4) y^(-4) = (-1/k) x + C,

where C is the constant of integration. Rearranging the equation, we have:

4y^(-4) = kx + C.

Finally, to answer the given options, the orthogonal trajectories for the family of curves y^6 = kx^6 are:

The parametrization of the intersection of the surfaces x² + y² = 64 and z = 6x² can be given by the vector function r(t) = (8cos(t), 8sin(t), 6(8cos(t))²).

Let's start with the equation x² + y² = 64, which represents a circle in the xy-plane centered at the origin with a radius of 8. This equation can be parameterized by x = 8cos(t) and y = 8sin(t), where t is a parameter representing the angle in the polar coordinate system.

Next, we consider the equation z = 6x², which represents a parabolic cylinder opening along the positive z-direction. We can substitute the parameterized values of x into this equation, giving z = 6(8cos(t))² = 384cos²(t). Here, we use the positive coefficient to ensure that the z-coordinate remains positive.

By combining the parameterized x and y values from the circle and the parameterized z value from the parabolic cylinder, we obtain the vector function r(t) = (8cos(t), 8sin(t), 384cos²(t)) as the parametrization of the intersection of the two surfaces.

In summary, the vector function r(t) = (8cos(t), 8sin(t), 384cos²(t)) provides a parametrization of the intersection of the surfaces x² + y² = 64 and z = 6x². The cosine and sine functions are used with positive coefficients to ensure that the resulting coordinates satisfy the given equations and represent the intersection curve.

The normal distribution for the heights of the 430 NBA players has a mean of μ = 89 inches and a standard deviation of σ = 4.89 inches. We need to find the probabilities for the given heights:a.

More than 95: We have z = (x - μ) / σ = (95 - 89) / 4.89 = 1.23

P (z > 1.23) = 1 - P (z < 1.23) = 1 - 0.891 = 0.109 = 10.9%

Therefore, the probability that a player is more than 95 inches tall is 10.9%.

b. Less than 56: We have z = (x - μ) / σ = (56 - 89) / 4.89 = -6.74

P (z < -6.74) = 0

Therefore, the probability that a player is less than 56 inches tall is 0%.

c. Between 80 and 110: For x = 80: z = (x - μ) / σ = (80 - 89) / 4.89 = -1.84

For x = 110: z = (x - μ) / σ = (110 - 89) / 4.89 = 4.29

P (-1.84 < z < 4.29) = P (z < 4.29) - P (z < -1.84) = 0.9998 - 0.0331 = 0.9667 = 96.67%

Therefore, the probability that a player is between 80 and 110 inches tall is 96.67%.

d. At most 99:We have z = (x - μ) / σ = (99 - 89) / 4.89 = 2.04P (z < 2.04) = 0.9803

Therefore, the probability that a player is at most 99 inches tall is 98.03%.

e. At least 66:We have z = (x - μ) / σ = (66 - 89) / 4.89 = -4.7P (z > -4.7) = 1

Therefore, the probability that a player is at least 66 inches tall is 100%.

Thus, the probability calculations for each of the given heights are as follows:

a. More than 95: 10.9%b. Less than 56: 0%c. Between 80 and 110: 96.67%d. At most 99: 98.03%e. At least 66: 100%.
